Description

Edge blowing device of pickling line Technical Field The utility model relates to the technical field of metallurgical pickling equipment, in particular to an edge blowing device of a pickling line. Background In the strip steel pickling production line, the push-pull type pickling line is one of the most widely applied pickling lines. The push-pull type pickling line mainly relies on a pinch roller of an uncoiler to push strip steel forward, when the head of the strip steel is bitten into a coiling machine for positioning, a shallow groove type turbulent pickling process is adopted to pickle the strip steel in a pushed state, then a wringing roller is used to wring the strip steel, so that products and impurities on the surface of the strip steel after reaction are removed, and finally the surface of the strip steel is cleaned through a spraying groove. Specifically, the traditional cleaning technology is that a pair of edge blowing devices for blowing compressed air to the cleaned strip steel are arranged at the outlet of a spray tank of a push-pull type pickling line, and the water accumulated on the upper surface and the lower surface of the strip steel is blown to the outer sides of the two sides of the strip steel, so that the water trace remained on the surface of the strip steel is removed. For example, an authorized bulletin number CN221453849U discloses an edge blowing device of an acid pickling line, which comprises an operation platform, a guide mechanism, a driving mechanism and two air knives and air knife racks, wherein the guide mechanism and the driving mechanism are arranged on the operation platform, two air knives are arranged on each air knife rack along the vertical direction, the two air knives are arranged on the guide mechanism in a sliding manner, the two air knife racks are symmetrically arranged about the middle point of the guide mechanism, the driving mechanism is connected with the two air knife racks, and the driving mechanism is used for driving the two air knives to move oppositely or move back to back on the guide mechanism at the same time. According to the design, the edge blowing device of the pickling line can adjust the distance between the two air knife racks, so that the distance between the two air knife racks is adjusted in real time according to the width of strip steel in the production process, the edge blowing effect of the strip steel after pickling is optimized, and the edge blowing device of the pickling line adopts automatic control to realize a dynamic adjusting function, thereby not only reducing the labor intensity of operators, but also improving the production efficiency of the strip steel.
